We are going to calculate the equivalent resistance in parallel circuits.
00:00:00
In parallel circuits, you don't add the two resistors.
00:00:05
When you have two resistors that are in parallel, this is the formula to calculate the equivalent resistance.
00:00:10
For example, here we have two resistors in parallel of 200 ohms and 300 ohms and the battery of 15 volts.
00:00:17
They ask you to calculate the equivalent resistance first.
00:00:26
Substitute this 200 and 300 into the formula.
00:00:31
1 divided by the equivalent resistance is equal to this.
00:00:38
Make this operation in the calculator.
00:00:42
Never use common multiples.
00:00:47
multiples 1 divided by 200 plus 1 divided by 300 it gives you this then
00:00:50
you have this value 1 divided by equivalent resistance and I need the
00:00:57
equivalent resistance so you look for this button in your calculator or this
00:01:04
one and you make the inverse of this figure or make this operation 1 divided
00:01:11
by the result you have obtained and then it gives you the total equivalent
00:01:17
resistance that in this case is 120 ohms. Look at the result and check that the
00:01:23
result is smaller than both of them. And finally to calculate the intensity go to
00:01:30
the Ohm's law. Intensity is voltage divided by resistance. Voltage of the cell
00:01:39
divided by the equivalent resistance and then make this operation and you have the total intensity
